Playing with this 19 C7 Z06. It dyno'd 524/576 stock. Added the AFE CAI and Borla X and it ran 10:77@132 at the track which I thought was very good for the summer. I then upgraded to the IW 18% overdrive crank. The car only dyno'd 592/699. Torque is great but HP seems to be on the low side. The curve kind of goes flat after 5500 rpm.
I could use a second set of eyes to see if something is being left in the tune. FWIW-the wideband is after the factory cat. That was only place I could install it cleanly.
